Is there a way to set up a password so no one can look at your voicemail if they're using your phone? I have noticed that if I call my voicemail it ask's for a password. So why doesn't it ask if im looking at my voicemails?
Not that this is the right answer but you can always lock your device with a passcode if you are that worried about your voicemail. If you think about it is it any different than SMS and email? Should you have to enter your password every time you want to see your email?
I wouldn't want to have to enter a password every time, but I agree that it should be an option. Sometimes you let someone use your phone and unlock it for them, but maybe you don't want them snooping around other stuff other than non-personal apps. Hell, I'd probably turn on the password feature JUST for when I let someone play with my phone.
